Disaster has struck - hard on the heels of the COVID-19 pandemic, another disease outbreak has hit your fair city, Malleith. Residents are outraged and worried. There have already been 13 deaths.
The cause of the outbreak appears to be methicillin-resistant Staphylococcus aureus (MRSA). (Please refer to the CDC MRSA Fact Sheet for more information about the pathogen.)

Each member of your group will play one of the following roles as you attempt to tackle the disease outbreak and save your city:
You must work together, using the information that has been provided for you in the attached information packets, and decide what action(s) should be taken to control the outbreak currently plaguing your city, Malleith. Your actions should be evidence-based – use the peer-reviewed literature to decide on measures that will stop the pandemic in your scenario.
Your action points may include directives to gather more information (e.g., contact tracing of current cases, microbiological testing of food/water, etc.), or specific directives (e.g. public health measures, non-pharmaceutical interventions, etc.). Use the data/expertise of all group members. Be clear, concise, and specific.
You should submit 3-5 specific actions to control the pandemic, using the workshop 3 pro forma (also available on MyPlace). Submit this by noon, Friday March 10th, via the submission link on MyPlace.
You are the provost of Malleith, elected in 2017.

Subject: This Sad Pandemic
Dear Provost,
I am so angry to hear about this new pandemic in Malleith. It seems almost like the apocalypse must be upon us, with this pandemic following so close upon the heels of COVID19.
I wish that your office is going to do something about dreadful state of affairs as soon as possible.
Yours sincerely,
Wilson

Subject: Pandemic Disaster for Businesses
Dear Provost,
This new pandemic in Malleith has the potential to destroy our businesses. I run a bookshop on the high street and virtually went bankrupt due to COVID.
I hope you realise how costly the last pandemic was for millions of people across the country, and that we can’t afford another one.
I hope very much that your office is going to do something about horrible pandemic as soon as possible, keeping in mind the economic interests of businesses in our city and the fact that we cannot afford a return to COVID rules.
Sincerely,
Eleanor (Bella’s, proprietor)

Subject: Government Overreach
Dear Provost,
I hate the idea that you and your office are going to use this new pandemic as yet another excuse for government overreach into citizens’ lives. Machiavelli said that power corrupts absolutely, and he was absolutely right - look at what happened during the last pandemic.
Please do not use this disaster as another opportunity for oppressive lockdowns and government control of our lives.
All the best,
Eleanor (a concerned voter)

Dear Provost,
I have just learned that my my niece has passed away due to the new pandemic in Malleith. You cannot begin to imagine the grief that we are feeling.
This is an unspeakable loss.
I am sure that you and your office are doing your best, but I hope that in the fullness of time, there will be a public inquiry into how this pandemic was handled and why so many families have lost loved ones. Especially coming so soon after the lessons that we learned during the COVID-19 pandemic, I would have thought that this tragedy could have been prevented.
Kind regards,
Anna

You are an epidemiologist working for Public Health Scotland, sent to Malleith to help with the MRSA outbreak.
A team of scientists working together have in a PHS lab have isolated and cultured MRSA from a number of patient samples taken during this outbreak; isolated genomic DNA from cultures of these isolates; sequenced this DNA using an Illumina MiSeq platform; assembled the short paired-end reads; and compared these assemblies to the extant Staphylococcus aureus sequences available in the NCBI databases. The results of these experiments are summarised in the table below.
